MOLDER'S FLASK Filed Oct. 28, 1929 2 sheets sneet 2 Wi/ard 135M072, Iwzzdfl W BY 01%} Patented Mar. 10, 1931 UNITED STATES PATENT OFFICE WILLARD A. MOORE AND KENNETH L. MOORE, OF MUN CIE, INDIANA MOLDERS FLASK Original application filed February 27, 1929, Serial No. 343,067. Divided and this application filed October 28,1929. Serial No. 403,020.

This invention relates to molders flasks and has especial relation to partition bars for the same, the present application being a division of an application filed by us February 27, 1929, Serial No. 343,067, and which eventuated May 27, 1930, into Patent The present invention has for an object the provision of a partition bar which may be quickly secured within or removed from the .flask, or may be adjusted to any desired position therein.

Other objects of the invention are the provision of a bar which may be positioned at any point along the sides of the cope for holding the sand therein; will materially reduce the number of jaggers used; may be adjusted vertically within the cope or drag, and may be longitudinally adjusted to provide a snug fit.

With the above and other objects in view,

' the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a plan view of a mold showing the invention in use, parts of the mold being broken away and shown in section.

Figure 2 is a sectional view through the mold showing the bar in elevation.

Figure 3 is a section at right angles to Figure 2.

Figure 4 is a detail perspective view of the mold.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the invention is shown in 40 connection with the flask disclosed in our application above referred to and which includes a cope 10 and a drag 11. The flask in the application mentioned is of the knockdown type, the walls consisting of interchangeable units. It is of course obvious however that the bar may be used with other typesof flasks.

As illustrated, the cope and drag are of similar construction and are provided along opposite walls with longitudinally extending ribs 12. These ribs are adapted to be engaged by the partition bar 13, which is provided along one edge with spaced recesses or teeth 14 for this purpose. The other end of the bar 13 is inclined as shown at 15 and s5 pivotally secured to this end of the bar as shown at 16, is a member 17. This member is provided with spaced recesses 18, similar to the recesses 14, so as to engage one of the ribs 12, and in order to hold the member 17 30 and the opposite end of the bar 13 in such engagement, a wedge 19 is provided. This wedge is inserted between the member 17 and the adjacent inclined edge 15 of the bar 13.

The bar may be adjustably raised or lowf ered, or it may be adjusted laterally to hold the sand within the cope. The bar also eliminates to a very large extent the number of jaggers used. The bar may be adjusted vertically to suit the mold and will provide a tight fit therein through the use of the pivoted member and wedge.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein 1': reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In a molders flask, a bar adapted to be removably positioned therein, interlocking means between the ends of the bar and the walls of the flask, and means to adjust the length of the bar to force the ends of the latter into locking position with said walls.

2. In a molders flask, a bar removably positioned therein, opposed ribs extending longitudinally along opposite walls of the flask, one end of said bar having recesses spaced along its edge to receive the ribs, a member pivotally secured to the other end of the bar and having recesses along its outer edge to receive the ribs, and means to force the pivoted member into rib engaging position.

3. In a molders flask, a bar removably positioned therein, opposed ribs extending longitudinally along opposite walls of the flask, one end of said bar having recesses spaced along its edge to receive the ribs, a member pivotally secured to the other end of the bar 303 and having recesses alon its outer face to recelve the rlbs, and a. we ge removably posltioned between the-pivoted member and the adjacent end of the bar to force said. pivoted member into engagement with the ribs.

In testimony whereof we aflix our signatures. V
